BOOK.

T @ZZ whom t may Concernf Beit knovvn that l, FRANK D. Foa'rnsr,

Va citizen ot the Unitedv States, residir; at

Brooklyn, county ot Kings, and State ot New York, have invented certainnew'and useful Improvements in Books, of which the following is a full,clear, and exact speciiication,

This invention relates ,generally to books, and particularly to boundvolumes otl that character wherein supplementary book sections are usedtherewith.

rThe .primary object ot the .invention is to provide a book and itssupplemental section o't such character that the said section may beremovably secured Within the book in such manner as to lill out thethickness or the same and thereby assist in preventingv collapsingl ofthe back of the permanently bound volume, and which enables the saidvolume to present an appearance ot completely filling out the spacebetween the front and back covers.

A further and particular object ot the invention is to provide a book ofthis character, the advantages ot which are apparent, featured by meansof an improved and simplilied nature for strengthening' or reinforcingthe back of the permanently bound book to prevent creasing or collapsingot the same. Y lVith these object-s in view, together With others whichWill appear as the description proceeds, the invention resides in thenovel construction, combination and arrangement of parts, all as Will bedescribed more fully hereinafter, illustrated in the drawing, andparticularly pointed out in the claim.

ln the drawing:

Fig. l is a perspective view of a book constructed in accordance withthe invention. a cover thereof being shoivn in raised position, and,

Fig. 2 is a transverse sectional view taken through the book with thecovers in closed position,

rlhe book or permanently bound volume comprises the front and back covermembers represented generally at 3, connected by the back memberLil-,the latter having` secured as by glue, stitching or other preferredmeans, the back edges of the sheets or leaves of the book represented at5. T he back and cover members may be formed ot cloth orheavy paper asdesired, and the book may vary in thickness accordinglyv as occasiondemands.

Associated with this permanently bound volume isa supplemental orremovable book section, the leaves ot which have secured thereto thecover members 7. The leaves of this supplemental volume may be securedto the back 8 thereof in a manner similar, as lesired, to the method ofsecuring the leaves et the main volume to its back.

In order that the supplemental volume may be associated ivithinthecovers ot' the permanently bound volume so as to lie properly Within thesame Without protrusion or bulging. the back l of the main volume is ofgreater breadth than the bot y oft leaves per se; the difference inbreadth being` substantially equal to the thickness ot the supplementalbook to be accommodated. One oi the cover members 3 ot the permanentlybound volume is provided upon its inner tace With a .pocket indicatedgenerally at 9 to receive one of the covers 7 of the supplemental book.rihe cover 7 to be inserted Within this pocket may have its lateraledges inclined as shovvn by dotted line in Fig'. l, so as to facilitateready insertion ot this cover member in said pocket.

That part or" the back l ot the permanently bound book which has noleaves secured thereto is reinforced or stayed by fr iiller member 10 ofsubstantial thickness, ot a breadth equal to the space to be illed, andof a length equal to the height of the pages or leaves 5 ot the volume.rllhis filler member may be formed of one or more plies of relativelyheavy cardboard or may be of Wood or suitable metal. In the presentinstance, for the purposes ot illustration, this filler member is formedott heavy cardboard, 9* and is I:glued or cemented securely to the. backel ot the volume. To ri gidly anchor this filler member in place, aswell as to lend rigidity and strength to the entire book structure, thefiller member l0 is glued or cemented innf'ardly `trom one end of afabric member ll ot a length substantially equal to that ot the leaves5. The inner tree end of this fabric is then passed around against andis glued to the back 4, with its extremity doubled back and glued Withinor between leaves 5 ot the volume a substantial distance from theadjacent edge ot' the filler member l0. rThe fabric member or anchor isextended across the cover 3 and is rigidly secured thereto, beingdoubledback upon itseli a substantial distance and secured at its edges toprovide the inwardly opening pocket 9 for the reception of the covermember i' of the supplemental boolr. It will be rndersteed. ot course,that the leaves of the supplemental bool: are substantially equal inlength and l` 'eaaltl"L to the length and breadth of the leaves 5 et'the permanently bound volume. The supnlemental volume is associated, asabove described. with the perinanentl7 bound rolunie in such manner asto have its edges substantially coincide at all times' with the edges 5or" the permanentlyv bound volume of leaves. Vfhen the cover member 25is opened, it carries with it the cover member T o'l' the supplementalbook, and 'lie pages ofi the latter may be used for notations desired.The leaves 6 of the supplen'iental i'olume are at all times availablefor use and may be turned as readilyY within the volume as removedtherefrom, and the presence ot the supplemental bool; within the corersof the main Volume in no wap1 interferes with proper manipulation oropening and closing' of the main volume. rlie supplen'iental volume thuslits within and forms a component part of the main volume7 and yet ma)vbe readil)Y removed therefrom and replaced when desired. rl`heparticular structure employed in reinforcing` the back preserves theconstruction of the latter as well as the appearance thereof. and dangerot cracking. tearing` or breaking of the same is obviated.

Haring thus described my intention, I claim:

'r book comprising a bach member, a pair of covers flexibly connected tosaid back, a set ot' leaves secured to said back, the top ot said setof' leaves tern'iinating short of the upper longitudinal edge oi saidback inember, a i'iller member (1U) located against the inner surt'aeeof said back member and e3:- tcnding a short distance outwardly thereofand filling' the space adjacent said back member between 'the upperlongitudinal edge of the latter and the top of' said set ot leaves.l alabric member tor anchoring' said filler member in place. said fabricmember beingy secured to the Jfront ot' said 'iller member' and haringits inner free end passed around against and secured to said back memberwith its evtremity doubled haelt and securedwithin ul set ot leaves. theother end ot' said :t'alnic member extending.` across the top cover,doubled upon itsel'i a substantial distance and serured at its edges todeline an inwardly opening` poel-iet, and a supplemental lioolt.comprising a cover member and having a body ot leaves substantiall)vequal in length and breadth to said set ot leaves associated with saidback member and sulstantia lj.' filling the space between the top ofsaid set of leaves and said top cover, one end of said cover memberbeing insertable within said pocket on said top corer for the purposespeciied.

In testimony whereof I a'lliX my signature.

FRANK D. FORTIEY.
